To all whom 'it may concern.'

vcitizen of 'the United States, residing in the city of Philadephia, county of Philadelphia., and State of ennsylvania, have invented certain Improvements in Pencils, otwhich ro el- This is a pencil aving means for ling ythe lead or` marking rod. Its ea 'ng object is -to provide a propelling pencil that is lnexpensive, simple and efficient; and to this end 1tl consists, in its preferred form, in

the use, in a suitable body, of a ratchet mechanism o erated'by a button for propelling the mar 'ng rod and a spring forretracting -theratch or rack.

In the accompanylng drawings, Figure 1 1s a sectlona'l elevation representing a form of the invention; Fig. 2 is an`elevation of a 20 catching device on a marking rod; Fig. 3 is an elevation of a section of a ratch with a button fixed thereto; Fig. 4 is a sectional elevation of a further form of the invention; F1g 5 1s an elevation of the detached ratch, sprmg and catches shown in Fig. 4, and Fig. 6 1s a sectional view of a further modification of the invention.

-to the end of the tube opposite the point, l the collar having an inturned flange 2.

.button or knob 3 has a flange 3 engaged within the collar by the 'flange 2', and a shank 3, adapted to reciprocate within the spring catches 6' and 6" thereon, is fixed to tube 1. -A se ental ratch or rackx4 with holes 4 therein the holes being disposed centrally or between the edges of the seg-- mental channel forming the ratch is fixed to the button shank 3 and lies within the ltube 1, where it is adapted to reciprocate, and a coiled spring 5 lies within the collar 2 between the head of the tube 1 and the button .flange 3. A band-'or collar 6, havingexpanding t e head of the lead or marking -rod 7 Within the tube 1, the catch 6 engaging the ratch 4 and the catch or spring 6" engaging the tube 1 to hold the catch 6 in engagement withv the ratch and tokprevent the rod 7 from heiligl drawn back in the tube 1. When the button 3 is pressed in', it thrusts the ratch 4- toward the point and propels the marking rod 7 through the engagement of the catch 6 with withdrawn, vwhilethe ead is held in the position to which it has been propelled by the en agement of the part 6 with the tube. In tie form of the invention illustrated in Figs'. 4 and 5, the tube 1, with the collar 2 -fixed to its top, and the button`3 acting within the collar, are combined with a ratch 4 connected bthe coiledv spring .5a to the tube within w 'ch' it reci rocates, one end of the coil being fixed to t e top of the ratch and the other end to the top vof the tube, the collar 6 fixed to the 'marklng rod 7 within the -tube having the s ring catch 6 for engaging the holes 4 in tie ratch and the s ring catches 6 for engaging the tube and ho ding the catch 6 to its work. As previously described, when the button 3 is pressed in, it advances the ratch 4, compressinor the spring 5, and the ratch acts through ttl with its catches 6 and 6 to propel the marking rod, the latter being held by the catches 6 against retraction with the ratch through the action -of the spring 5a on releasing the button. L

In the form of the invention shown in Fig. 6, the tube 1 has 'the collar 2 fixed to the top thereof and contains the ratch 4*il which has its top fixed to the top of the tube by the coiled spring 5 within the collar. The button 3 (with the flange 3 within the tube for engaging the flange 2 on the collar and the 1e collar. 6

action of its catches 6 and 6", 'thus' propel- 1 ling the marking rod 7. The deepest part of the cam having passed the highest part ofthe 4 spring, the latter expands and retracts the ratch, the holding mechanism. on the markingrod maintaining the latter inthe position to which it has been propelled.

- Having described my invention, I claim 1. A pencil having a hollow body, a markin rod movable in said body, a catchfixed to said rod, a segmental rack with 4means between the edges thereofA for engaging said catch tol ro el said rod, a catchfor holding said catc said rack and engaging said body to prevent the retraction of said rod, and a button for operating said rack.,

2. 'A pencil having a hollow body comprising a cylindrical tube. formed by winding sheet material, a marking rod movable in said tube, a perforated channel movable in said body, elastic catches fixed to said rod, one of said catches en aging the perforations of said channel and t e other vengaging said body, a movable button for operatin said channel, and a collar ixed to said bo y for controlling the movements of said button.

3. A pencil havin a hollow body, a ratch movable in said bo y, a marking rod movable in said body, catches fixed to said rod so as to engage said ratch and said body, a revost named in engagement with.

Aluble device having a cam connected with said ratch so as to move it 1n said body, and

means for en aging said device to said bod I 4. A pencihaving a hollow body, a mar in rod movable in said body, a catch on said ro, a rack movable in said body to en age 'said catch and propel said rod, a s ring ed to said body and rack to retract t e latter, a button movable to propel said rack, `and'a collar engaging said button to said body, said collar being fixed to said body and loosely e aging said button.

n testimony whereof I have hereunto set my name this 13th day of December, 1907, 1n

the presence of the .subscribing witnesses.
